Need help ID'ing IC for PCB software

Postby kpeters59 » Mon Jul 31, 2017 3:36 pm

Hey folks!

I'm new, so please be gentle...

I got this crazy idea that I might be able to design a circuit for something I'd like to do.

The chip I'd like to use is an odd package and I can't find any details on it, except for what I received from the New Old Stock re-seller. Here's what he gave me:

Looking down at the chip flat it is 25mm wide x 23 mm high. Sitting on the pins, brings the chip 12mm off the surface. Pins extend about 4mm below the base of the chip. Pins are space about 2.5mm. Dip 16 at about 28mm between each row of pins.

Does anybody know what 'package' I would specify in a PCB Design Software? I tried Pad2Pad and PCB123, but was unable to determine the correct chip.

Barring that, I guess I'll need to figure out how to manually enter the 'footprint'

Thanks,

-Kyle Peterson

I think it is a reed relays from Datron. Similar an SM-C-500284 http://www.parttarget.com/5945-00-727-0479_5945007270479_2B-1518.html/-10224BB5-225F-41EF-AB74-A92BCE26078A. I think the dimensions are the same like DIL 16 0,1" pitch but a wide of 1,10" = 27,94mm. Not so difficult to draw in a PCB program like Eagle.

Thanks for replying!

It's definitely Reed Relays. Four of them, actually.

I haven't used Eagle, yet, but did find what appears to be a 'free' copy. I'll get it installed and try it out.

I had briefly tried to add a 'footprint' in both of the two programs listed above. I suppose that that all seems to be fairly straight-forward.

Does

"DIL 16 0,1" pitch but a width of 1,10" = 27,94mm"

actually translate to direct info that would be entered in Eagle?

I guess I'm hoping that if I can add the 'package' as a known size, that would be the most accurate.

I know for this chip that 'knowing' the pin-out isn't likely to happen, but is that too much to hope for with other, better known, chips? Where the 'nets' are added automatically?

Thanks again,

-Kyle

OK...so I looked at adding a "footprint" for that chip in Eagle and I didn't make ANY progress.

Could anybody give me a leg up on getting started?

In P2P and 123, adding a footprint was fairly obvious, but in Eagle, I can't even find a starting point...

Thanks,
